Loop through HashMap...

[patnim17]

Hi,
I need to loop through a HashMap object which has Key and Value pairs, both of type String, but I do not know any of the Keys or the values...
How can I loop through this HashMap and get both the Key and the Value in one loop...

The reason I want to get the Key and the Value in one loop is to build a XML out of it...

Thanks in Adv.
Nims..

You can obtain a set of keys with keySet() and iterate through it obatining the values.

Hi,
thanks a lot. Is it possible to get the data, value from a HashMap using the index..like say if I have key-value pairs in my HashMap as
1."cow"-"Milk"
2."Dog"-"Bark"
etc...is it possible to get the key-value pair by index..something like HashMap(0) ..

Use an ArrayList instead of a HashMap, then you can access elements by index.
